Hey guys, finally got my lm4! Just trying to get the delta ring back to remove the hand guards for replacement and I can't get them back. It's like they're glued or something. Could anyone shed some light on the problem?

It takes a considerable amount of force to push back the delta ring the first time. easiest way is to set the gun vertical and push on it while you're standing up. If that doesn't work, there are tools available to make removal of hand guards easier.
